NATHANIEL A. BOYNTON, OF NEW' YORK, N. Y.

FIRE-PLACE HEATER.

SPECIFICATION forming part of Letters Patent No. 444,987, dated January 20, 1891.

Application filed May 1l, 1885. Serial No. 165,078. (No model.)

To a/ZZ whom. t may concern.-

Be 1L known that l, NATHANIEL A. BOYN- TON, of the city, county, and State of New York, have invented certain new and useful Im provements in Fire-Place Heaters, of which the following is a full, clear, and exact description.

This invention relates to that description of fireplace heaters commonly known as Baltimore fire-place heaters;7 in which the body of the heater, that is of a close or stove-like construction and is generally furnished with doors and transparencies in front, is combined with and arranged to project largely in front of a frame or plate of any desired pattern, ornamental or otherwise, made to close in the lire-place about the body and base of the heater.

My invention consists in a certain combination of ues or passages for the escaping products of combustion with the body of the heater, its base, and the fireplace frame or plate inclosing the rear portion of the bodj7 and base of the heater, including fiues arranged down either side of the body in front of said plate or frame, whereby the heat is more thoroughly utilized within the apartment in which the heater is situated.V

Reference is to be had to the accompanying` drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts `lin all the figures.

Figure l represents a horizontal section of the heater upon the line :r ne in Fig. 2. Fig. 2 is a vertical section of the same on the line y y in Fig. l, and Fig. Sis a vertical section upon the line .af .2' in -Fig. 2.

A is the body, lire-chamber, or tire-pot of the heater, arranged to occupy a central position in the heater and of the usual or any suitable construction; B, its fuel cylinder or feeder; C, its grate, and D its basc,inclosing the ash-pit b.-

E is the plate, ire-board, or frame which closes in the tire-place about the body and base of the heater, and in front of which a large or the front portion of the body ot' the heater projects, as usual.

G G. are tubes or ilues arranged down either side of the bodyA in front of the plate or frame E. These front and exposed side fines G G connect at their upper ends, as by branches c c, with the upper portion of the body A, and at their lower ends with side fines d d, arranged in the base D on opposite sides of the ash-pit l), and from which upwardescape tlues c e, at the rea-r ends of the flues d d, preferably merging into a single flue above, project to carry off the escap ing gaseous products of combustion and establish the necessary draft.

By the arrangement of the fines G G down or on opposite sides of the bodyA of the heater, outside of the plate or frame E, the highly-heated gases of the products of combustion as they leave the fire-chamber and body A will contribute very sensibly by the exposed position of said tlues to warm the apartment in which the heater is situated, and said fines by their prominence will also give a more ornamental appearance to the heater.

'The fuel is or may be supplied to the feeder B bv opening a door g, arranged to close the mouth end of a hood v,It on the cover 'i' of the feeder beneath a plate 7e, which projects from the front of the frame or plate E of the heater.

It should here be observed that the tubes G G are both purely doWntake-flues and that they stand out well in front of the iir-e-board E, being wholly in front thereof; also, that the lower side fines (l d constitute two horizontal ground-hues leading under and behind the tire-board to a rea-r uptake inverted-Y Hue, formed by the uptake-dues c c merging into a single one, as described. This combination and arrangement of the tlues, fire-pot, and lire-board makes the fire-place heater to essentially differ from other lire-place heaters, in which the gaseous products of combustion are allowed to escape directly from the tire-pot or body of the heater through flues in rear ofthe lire-board, and it differs also from other fire-place heaters provided with various ascending and descending lues, including fire-place heaters provided with a reboard and heat-radiating side columns forming part of the indirect-draft flue and arranged to project only partly in front of the tire-board and constituting the one a downtake and the other an uptake-flue for use in connection with a heat-radiating box having deilectors to control the current. In my fire- IOO place heater, as hereinbefore described, the dues G :lr are both downtakes, and wholly. stand out in front of the fire-board, and the escaping heat is concentrated in front for use in the apartment in which the heater stands.

I do not claim as my invent-ion any of the parts herein described, separately considered, and disclaim each and all of the several inventions shown and described in the following patents, to wit: the magazine-stove in Patent No. 31,480, issued February 19, 1861, to S. T. Savage, in which a base -lourning chamber and external case have combined with them specially-arranged partitions and parts, whereby an indirect draft is produced around the front, sides, and back of the stove; the heating-stove described in Patent No. 24,241, to G.II.R1'1ssell,l\lay 31,1859,iu which an inner fire-drum, cold-air base, vertical side pipes, and elbows, with dampcrs and cylindrical cover or top drum, with various' chambers and connectingtube, horizontal airspace, and other parts, including` front vertical register-pipes, and foot-warmer connecting-pipes were used; the fire-place stove described in Patent No. 163,233, of Il. P. Ohm, in which were combined detlectors, the., with certain outstanding radiating columns only partially exposed in front and forming the one an uptake and the other a downtake; the base-burning stove shown in Reissued Patent No. 6,884, to S. B. Sexton, January 25, 1870, and having one or more side columns arranged to lead into a hollow base and connecting indirectly with the chimney-flue; the {ire-place heater in Patent No. 17 (5,070, issued May 2, 1876, to J. A. Lawson, also using side pipes in connection with a bottom flue, side bottom fines, and a back pipe extending upward and laterally and uniting above, and the base-burning ire-place heater in Patent No. 94,320, August 31, 1800, to Philip Klotz, in which vertical flue columns terminating above in a chamber formed bv a horizontal section extending laterally from the firechamber all around are used. In each and allof these structures the combinations shown are different from the combination which makes up my improved {ire-place heater, with its two advance downtake-tiues wholly in front of the nre-board, and which has for its special object increasing the power ol heat-radiation within the apartment in which the heater stands.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, in a nre-place heater, of a heater-frame, a fire-box, a combustionchamber over the same, front vertically-descending fines arranged wholly in front of the frame and connected directly to the combustion-chamber, horizontal rearwardly-extending` base-fines, and exit-fines or smokepipes. l

2. The combination, with a heater-frame and a iire-place heater having its combustionchamber extending in front of the frame, of direct vertical doWndraft-iueslocated in front of the frame and connected directly to the combustion-chamber in front of the frame, independent horizontal rearwardly-extending side base-flnes on each side of the heater, and exit-fines 6r smoke-pipes at back of the heater.

3. The combination, with a heater-frame and a lire-place heater, of a crown having side extensions in front of the frame, direct vertical downdraft-tlues located in front of the frame, and base-fines connected by said vert-ical lines with the extensions and extendin g rearwardly to the exit-fines.

i. In a lire-place heater, the combination, with the body, tire-chamber A,A fire-board E, and base D, of the upper side fines or branches c c, connecting with the body of the heater at its top, the exterior downtake-iiues G G in advance ot' the tire-board and center of the body ot the heater and arranged to connect the upper branch fines c c with the base D, the horizontal ground-dues d d, leading under and behind the tire-board, and the uptake and Y flue in the rear, all as herein shown and described, whereby the side downtake-iiues G Gr have a prolonged radiatingsurface extending from the top of the heater to its base, as set forth.

NATHANIEL A. BOYNTON.
